The remote OracleVM system is missing necessary patches to address critical security updates :

CVE-2009-1192 The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel before 2.6.30-rc3 do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensitive information by reading these pages.

CVE-2009-1072 nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

CVE-2009-1758 The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in 'certain address ranges.'

CVE-2009-1439 Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and earlier allows remote attackers to cause a denial of service (crash) via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.

CVE-2009-1633 Multiple buffer overflows in the cifs subsystem in the Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c  or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.

CVE-2009-1630 The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.

  - [agp] zero pages before sending to userspace (Jiri Olsa)     [497025 497026] (CVE-2009-1192)

  - [misc] add some long-missing capabilities to CAP_FS_MASK     (Eric Paris) [499075 497271 499076 497272]     (CVE-2009-1072)

  - [x86] xen: fix local denial of service (Chris     Lalancette) [500950 500951] (CVE-2009-1758)

  - backport cifs support from OEL5U3

Security fixes :

  - several flaws were found in the way the Linux kernel     CIFS implementation handles Unicode strings. CIFS     clients convert Unicode strings sent by a server to     their local character sets, and then write those strings     into memory. If a malicious server sent a long enough     string, it could write past the end of the target memory     region and corrupt other memory areas, possibly leading     to a denial of service or privilege escalation on the     client mounting the CIFS share. (CVE-2009-1439,     CVE-2009-1633, Important)

  - the Linux kernel Network File System daemon (nfsd)     implementation did not drop the CAP_MKNOD capability     when handling requests from local, unprivileged users.
    This flaw could possibly lead to an information leak or     privilege escalation. (CVE-2009-1072, Moderate)

  - Frank Filz reported the NFSv4 client was missing a file     permission check for the execute bit in some situations.
    This could allow local, unprivileged users to run     non-executable files on NFSv4 mounted file systems.
    (CVE-2009-1630, Moderate)

  - a missing check was found in the hypervisor_callback()     function in the Linux kernel provided by the kernel-xen     package. This could cause a denial of service of a     32-bit guest if an application running in that guest     accesses a certain memory location in the kernel.
    (CVE-2009-1758, Moderate)

  - a flaw was found in the AGPGART driver. The     agp_generic_alloc_page() and agp_generic_alloc_pages()     functions did not zero out the memory pages they     allocate, which may later be available to user-space     processes. This flaw could possibly lead to an     information leak. (CVE-2009-1192, Low)

Bug fixes :

  - a race in the NFS client between destroying cached     access rights and unmounting an NFS file system could     have caused a system crash. 'Busy inodes' messages may     have been logged. (BZ#498653)

  - nanosleep() could sleep several milliseconds less than     the specified time on Intel Itanium&reg;-based systems.
    (BZ#500349)

  - LEDs for disk drives in AHCI mode may have displayed a     fault state when there were no faults. (BZ#500120)

  - ptrace_do_wait() reported tasks were stopped each time     the process doing the trace called wait(), instead of     reporting it once. (BZ#486945)

  - epoll_wait() may have caused a system lockup and     problems for applications. (BZ#497322)

  - missing capabilities could possibly allow users with an     fsuid other than 0 to perform actions on some file     system types that would otherwise be prevented.
    (BZ#497271)

  - on NFS mounted file systems, heavy write loads may have     blocked nfs_getattr() for long periods, causing commands     that use stat(2), such as ls, to hang. (BZ#486926)

  - in rare circumstances, if an application performed     multiple O_DIRECT reads per virtual memory page and also     performed fork(2), the buffer storing the result of the     I/O may have ended up with invalid data. (BZ#486921)

  - when using GFS2, gfs2_quotad may have entered an     uninterpretable sleep state. (BZ#501742)

  - with this update, get_random_int() is more random and no     longer uses a common seed value, reducing the     possibility of predicting the values returned.
    (BZ#499783)

  - the '-fwrapv' flag was added to the gcc build options to     prevent gcc from optimizing away wrapping. (BZ#501751)

  - a kernel panic when enabling and disabling iSCSI paths.
    (BZ#502916)

  - using the Broadcom NetXtreme BCM5704 network device with     the tg3 driver caused high system load and very bad     performance. (BZ#502837)

  - '/proc/[pid]/maps' and '/proc/[pid]/smaps' can only be     read by processes able to use the ptrace() call on a     given process; however, certain information from     '/proc/[pid]/stat' and '/proc/[pid]/wchan' could be used     to reconstruct memory maps. (BZ#499546)

The system must be rebooted for this update to take effect.

    This issue does not affect prebuilt Debian kernels.

  - CVE-2009-1046     Mikulas Patocka reported an issue in the console     subsystem that allows a local user to cause memory     corruption by selecting a small number of 3-byte UTF-8     characters.
